Every time you exercise, jog for at least 40 minutes, then do the corresponding equipment training, and finally do waist and abdomen exercises. For the exercise of waist and abdomen, it is not limited to sit-ups, but also can be stimulated by low-weight squats, frog jumps and leg lifts. In order to reduce fat, simple sit-ups will be adaptable to abdominal muscles after a long time, so taking all kinds of waist and abdomen exercises I mentioned above will be effective.
Abdominal muscles can be practiced every day, and exercise is guided by the feeling of the body. If you feel tired, you should have a rest.
